All Things Considered, January 31, 2005 · Adam Curry, the former MTV VJ, is the star of a new broadcasting medium.

Instead, it's a podcast, so-called because it's delivered via the Internet directly to iPods and other personal listening devices.

The podcast pushes the range of personal online rantings to something close to an international radio broadcast. And as NPR's Nathan Santamaria reports, the quality is low, but the hopes are high.
